Wayland breaks professional software, that's bad enough:

I used kicad quite a lot. So wayland is a no. X is and will be.

I agree with rolfie,
Your laptop computer seems to be fairly recent. That means it's no use to fiddle with MBR and Legacy BIOS modes.
To successfully install Devuan Daedalus:
- completely reset your BIOS/Firmware settings and
- DISABLE just "Secure Boot"
- boot your PC with a Daedalus USB stick
- wipe the disk completely
- let the setup program configure your disk
- modify the setup to reduce the root filesystem
- add a /home partition (ext4) into the now free place
  (of course you can set up any partition you like, but leave the EFI partition unchanged)
- let the installer do it's work
- Then reboot to check if the system behaves as planned
- Now you may re-install as you like, but leave the boot structure unchanged, then it should work well.

BTW, EFI (UEFI) mode with Secure Boot disabled and the disk in GPT mode is preferable.
Possibly you don't need my advice, still, sometimes it's good to be reminded of it.
Good luck

Exactly,
the same old problem with the resolution of these "round-robin" DNS names resurfaces again and again.
I had to switch from my old, trusty own DNS named server (BIND) to the typical service-provider setup and that made me unhappy again.
The only solution was and is to replace "deb.devuan.org" with somewhat "XY.deb.devuan.org" in the /etc/apt/sources.list file, replacing the XY with the nearest mirror-country-code.
I don't know what HPFM is behind all these silly ISPs.
I'm not good enough to know how the Devuan community could set up a /etc/apt/sources.list file that would remedy the situation for once and ever.

Thank you for that precision

Hello
remembering from the days when I used HP printers (Print/Scan/Copy) on Devuan Daedalus:

All I had to do is:
install
-cups
-hplip
-hplip-data
-hplip-gui
-python3-pyqt5 (Python 3 bindings for Qt5)
Including all dependencies from the Devuan Daedalus repos only. And it rocked.

Now I'm using Brother MFC devices. With these I don't even have to install tools or drivers, just CUPS. The printer just works once connected to my local network (LAN). And it rocks even more. So cool.

Look at this thread:
https://dev1galaxy.org/viewtopic.php?id=6834
All I can say is this: most probably a provider's  configuration is to blame. If the provider is worth a thing, you could ask them to resolve that erroneous configuration of the provider's DNS-/Firewall- or Box-setup.
If not: a work-around is noted in that thread:
(--> Using deb.rr.devuan.org in /etc/apt/sources.list works perfectly well, as do all (most) other mirrors. <--)
Devuan and its OS is great and works really well. Thank you, Devuaners!

Thank you Ron, this is very good information - and a time-saver for many!

I based the Linux courses i developed on these resources as well.
Have a look.

Dear Unixuser,
as a unix user, you would certainly know the InitSysV, it's the default in Devuan. But you can choose OpenRC during the installation. If you are familiar with, what holds you back? It's my favourite and I'm happy with it.
Another remark: it's a mighty bad idea to install packages from Ceres when you use Daedalus, see the remarks from quickfur. Always stick to the chosen release.
If firefox-esr is not what you want, then you can install the tar.gz file from the Mozilla download site:
https://www.mozilla.org/en-US/firefox/download/thanks/
firefox-130.0.tar.bz2. I always use the 64bit version. There are instructions to follow. Ideally put the extracted files into /opt/firefox.
Make your own desktop-launchers..... some fiddling required, but all subsequent updates are painless and easy.
Good luck. (an old Unix pro of olden times)

@Altoid
I temporarily disabled the NetworkManager to acquire the DNS address from the local DHCP server, and set the nameserver to 8.8.8.8, as you requested.
After restarting the network-manager, for the first time deb.devuan.org was resolved by a ping request! Thanks a lot!

Now I reset the default Network-Manager configuration, and deb.devuan.org is not resolved again.
That proves that nothing is wrong with deb.devuan.org, nor with my workstation.

The local ISP provides the DNS service by the means of that cable-modem box, and the culprit really is the ISP.
Just as a side note: deb.debian.org was always resolved correctly by ping queries.

That concludes the matter and I thank you all for your hints and kind suggestions.
I will close the case.
Have a great weekend! with or without snow ;-)

Sure:

andre@yokohama:~$ cat /etc/resolv.conf 
# Generated by NetworkManager
search home
nameserver 192.168.1.1
nameserver XXXX.XXXX.XXXX.XXXX.XXXX.XXXX.XXXX
